Mixtures can either be homogeneous or heterogeneous. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.A heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present.One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures.A homogeneous mixture in which there is both a solute and solvent present is also a solution.ir is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.

Why does it glow blue? It's the Cherenkov radiation: 'Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium.' It's going faster than the speed of light (in water).
Blue light is a colour in the visible light. spectrum that can be seen by the human eye. Light is made up of electromagnetic particles that travel in waves. These waves emit energy, and range in length and strength. The shorter the wavelength; the higher the energy. The length of the waves is measured in nanometers (nm), with 1 nanometer equaling 1 billionth of a meter.
